voYER AND ONE-THIRD TO B. HfMoNAHaN, BOTH or MINNEAPOLIS, MINNESOTA. SHEET MATERIAL FOR CONSTRUCTION PURPOSES. Application filed April 30,, 1928. Serial No. 274,128.

My invention relates to sheet material for side portions converge toward a median line. construction urposes and while not limited The ang e of inclination of the corrugations in regard to ind of material, I consider it is dependent uponwhether or not it is desired particularly applicable to sheet metal. An that the plate shall have the same stiffness for object of the invention is to provide the sheet both the longitudinal, and transverse axes material with a plurality of corrugations so thereof. Except for the corrugations which arranged as to greatly strengthen the mateare located in the two lower corners of the rial both lengthwise and crosswisej The sheet plate as shown-in Fig. 1, the corrugations of material is made in the form of plates of a the two side portions meet each other so as to 10 size convenient for handling and for many form apices located in the median line of the purposes a plurality of these sheets or plates plate. If the two sets of corrugations were may be joined together at their edges by an caused to meet each other in the form of sharp overlap secured in place in suitable manner apices, there would be a line of weakness coas by welding, riveting, bolting,'etc. The incident with the median line. Therefore, I 15 joints will referably be welded together in round the apices and also preferably extend order to ma e them airtight and liquid tight the rounded apices downwardly so as to give when the plates are put together in such manthem a downward bulge or flare as .indicated ner as to produce articles such as gas tanks, oil at 16 whereby the plate is strengthened .tanks, culverts, round or otherwise, waterlengthwise along the median line. Inthe 20 pipes, water tanks, and other liquid holding form shown in Figs. 1 and 2, the two side V tanks as well as tanks or bins for holding margins of the plate are left with similarly flour and other powdered substances. The placed flat portions as indicated at 18 so that sheet material may be employed for roofing different plates can be butted together and a. either in flat, round, ;or curved condition. flat strip 20 secured in suitable manner over 25 Riveting or bolting if found more convenient the joint. In. the form shown in Fig. 3, the may be employed for producing forms for butting edges of two adjacent sheets respecconcrete work and sheeting for barns, silos, tively are formed with fiat portions 22 and cars, sheeting for airplanes, and frame work 24, the later extending out at a slightly hig of all kinds. er position than the other so that the two flat The full objects and advantages of my in portions may be overlapped and secured tovention will appear in connection with the gether. The'two flat portions when properly detailed description thereof, and the novel secured together are given additional features of my inventive idea will be particustrength on account of the increased thicklarly pointed out in the claims. ness otthe material. In the form shown in 35 In the accompanying drawings which il- Fig. 4, the corrugations extend entirely to the 9.0 lustrate the applicationof my invention, Fig. side edges of the plate, and in such case, the 1 is a perspective view showing a portion of a plates two of which are indicated by the charplate and the abutting edge of an adjoining acter 10 are secured together by a strip 26 plate. Fig. 2 is an end view showing two which is corrugated in such manner as to fit I 40 plates butted together and the joint covered snugly upop the corrugations of the butted with an overlapping flat strip. Fig. 3 is an plates and cover the joint. This strip is end view showing two plates with their edges welded or'riveted to the butting edges. The overlapped.

Sheet material for construction purposes that corresponding corrugations of the two comprising a plate having corrugations sponding corr other at saidmiddle line by means of rounded elongated apices.

3. Sheet material for construction purposes comprising a plate having corrugations formed diagonally therein so as to converge toward the middle line of the plate, correugations merging into each other at said middle line by means of rounded apices, and the opposite sides of said plate having flat margins.

Sheet material for construction purposes comprising a plurality of juxtaposed plates, each of which has corrugations formed diagonally therein so as to converge toward the middle line of the plate, corresponding corrugations merging into each other by means of rounded apices, the adjacent edges of said plates butting against each other, and a strip lapped over said butting edges.
